French-born, New York-based street artist WK Interact has been creating perpetual-motion-intensive black-and-white site-specific works for a quarter of a century, interacting with urban environments around the world. His swirling, sprawling manipulated photocopy projects, like his 2011 “Project Brave” tribute in Brooklyn to the heroes of 9/11 on the tenth anniversary of the tragedy, can be found on walls and buildings as well as in art galleries. His latest show, “WK 360: A Mid-career Survey Documenting 25 Years,” comes to a close at Jonathan LeVine’s pop-up gallery on West 23rd St. in Chelsea on Saturday, and it’s going out in a big way. Starting at 4:00, all guests will receive a free copy of the exhibition catalog. At 5:00, WK will give an artist talk, and he will also sign copies of his monograph and a 30x40-inch map (both available for purchase) of the locations of his artwork in Lower Manhattan over the years.
